Big Time Gaming

Big Time Gaming (BTG) is the Australian studio that changed online slots forever by inventing Megaways, the variable-reel mechanic that can deliver up to 117,649 ways to win on a single spin. Founded in 2011 and headquartered in Sydney, BTG not only builds its own acclaimed games but also licenses the Megaways engine to dozens of other studios, which has made it one of the most influential developers the industry has ever seen.

Bonanza and the Megaways catalogue

The game that started the Megaways revolution, Bonanza, remains a genuine fan favourite, and its successor Bonanza Megaways — along with Extra Chilli, White Rabbit, The Final Countdown, Danger High Voltage and Lil Devil — showcases BTG's love of high volatility, cascading reactions and enormous win potential. Many BTG titles reach maximum wins of 10,000x your stake or more, with an average RTP around 96.0% and configurable feature-buy options on newer releases.

How Megaways changes the odds on every spin

Mechanically, Megaways works by randomly assigning a different number of symbols to each reel on every spin, so the number of ways to win constantly changes. Combined with cascading Reactions — where winning symbols disappear and new ones drop in — and unlimited win multipliers during free spins, the format produces the unpredictable, explosive sessions BTG is famous for. The studio has since extended its inventiveness with mechanics such as Megaclusters and a range of bonus-buy formats.

Why other studios licence the mechanic

That engineering-led, quality-over-quantity philosophy means BTG releases fewer games than the biggest studios, but its influence is everywhere: because Megaways is licensed so widely, you will find the brand's mechanic across virtually every major operator, even on games built by other developers. BTG's own titles are fully mobile-optimised and remain lobby staples years after release.

Who Big Time Gaming slots are for

Because the variance is high and the maths can swing dramatically, Big Time Gaming slots suit players who enjoy unpredictability and understand that big Megaways wins are rare but potentially huge. As always, start in demo mode and never wager more than you can afford to lose.

Getting comfortable with shifting reels

Getting comfortable with Megaways is the key to enjoying Big Time Gaming slots. Because the number of ways to win changes on every spin and the real money is made during the cascading free spins with their unlimited multiplier, the base game can feel quiet for long stretches — that is normal for this high-variance format. A smaller stake relative to your bankroll lets you ride out the dry spells while you wait for a big multiplier to build. Check the RTP version on offer, since Megaways titles are frequently configured differently by operators, and look at the max win to gauge the upside. Every BTG game on our site is playable in free demo mode, so you can see how Bonanza Megaways and its Reactions work before committing real funds.

If you enjoy the unpredictable thrill of shifting reels and six-figure ways to win, Big Time Gaming is the studio that pioneered it all.

Big Time Gaming against the studios we also review

A studio is judged less by how many games it ships than by how consistently it delivers and which regulator signs off its RNG. Big Time Gaming has been shipping for 15 years. The table places it in the field we cover.
